    Thermador oven question

    O.k. here goes.
    I have a thermador convection oven/microwave/warming drawer oven
    mod.# semw302. 9 months old. In the self cleaning mode after about 1 hour i get an erro code F-34. Factory rep/service man comes over, pulls unit & installs more insulation & a side vent gizmo. He says it`s a manufactue update fix. I try self clean last night & it`s still comes up F-34 erro code.
    What the h--l is F-34?????????. And don`t tell me to check super heat

    I think anyone who can afford a Thermador can afford someone to fix it for them.

    Trust me, I know what I'm doing.

    F-34= upper oven air switch located either under oven or on rear depending on ser #. Remove vent and look to see if they are below,upper is on l/s. If not there they are on rear of oven.This trouble is impossible to diagnose unless it is in solid. Trouble could be air sw, connectors,loose connection on board or board itself.

    F34 Upper oven cooling fan over-speed or
    under-speed detected

    I can see this is going to be a lot of fun.
    no d or j done, over sized? yes....
    collin, this remodle job was my wife`s idea, not mine.I made her pay for everything. I was happy with my 1934 stove.
    They did replace the side vent with a factory replacement.
    Air switch, circuit board???? Modern technology is wonderfull.

    To me it sounds like that they have a sensor detecting a temp to high going out the vent or it could be the sensor itself.

    For what the tech did was propley something that the manufactor is trying to do to slove this problem and you are not the first one with it.

    I know I have had a situaton with this in a kitchenaid brand a few years back.

    I replaced it twice and then come to find out that the sensor over time "because of heat" would turn just enough to touch the side of the cabinet and short it out.

    Now look at this that I found

    I copied and past it

    BSH Home Appliances Corp. Recalls Thermal/Microwave Ovens
    Los Angeles, CA (SafetyAlerts) - BSH Home Appliances Corp. said today it is recalling about 2,300 Thermador® brand combination thermal/microwave ovens. The oven door may not lock properly when the oven is put into the "self clean" mode. While the oven is in "self clean" mode, intense heat is generated to clean the oven. If oxygen is introduced by opening the oven door during the "self clean" mode, combustible material left inside can ignite and pose a fire risk.

    The oven has a steel frame around glass panels and comes in a black, white or stainless steel finish. It is sold as a single or double-stacked unit. The model numbers included in the recall are CM301UB, CM302UB, CM301UW, CM302UW, CM301US, and CM302US with serial numbers that begin with 2003 through 2010. The model and serial numbers are located on a data plate inside the grill located beneath the control panel that reads "Thermador" on the right hand side of the oven.

    Appliance and specialty stores nationwide sold the ovens to homebuilders and contractors from about May 2000 through May 2001 for about $3,000 to $4,600.

    INCIDENTS/INJURIES: None reported.

    Consumers should stop using the "self clean" mode of the recalled ovens immediately and contact Thermador at (800) 735-4328 between 5 a.m. and 5 p.m. PT Monday through Friday to arrange for a free inspection and if needed, free repair. Media inquiries should be directed to Gary Ball at (714) 899-4166.
